Justin Bieber was all about the older women at the 40th Annual American Music Awards at the Nokia Theatre in Los Angeles on Sunday Nov. 18.

The 18-year-old was the night's big winner with three major trophies: Artist of the Year, Favorite Pop/Rock Artist and Favorite Pop/Rock Album. His date for the fete wasn't estranged love Selena Gomez but another very special woman: His mother, Pattie Mallette.

"This is for all the haters who thought maybe I was just here for one or two years," the "As Long As You Love Me" singer said accepting his first award of the night. "I feel like I'm gonna be here for a very long time."

Bringing his mother, 38, onstage for his final win (Artist of the Year), he sang her praises to the crowd "This is my mom. She's little, but she's beautiful . . . It's hard growing up with everything going on, with everyone watching me. I wanna always make you proud."

It was a slightly more awkward moment onstage earlier in the night for the teen sensation when he accepted an award from Jenny McCarthy. Just two years older than Mallette, the former Playboy model, 40, congratulated Bieber for his win by showering him with kissing and aggressively groping him onstage.
